Given numbers are 688,566,561,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,566,561,849 is 109228944.
Find LCM of 688,566,561,849 with Prime Factorization
| 2 | 688, 566, 561, 849 |
| 3 | 344, 283, 561, 849 |
| 283 | 344, 283, 187, 283 |
| 344, 1, 187, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 283 x 344 x 1 x 187 x 1 = 109228944
Therefore, the lowest common multiple of 688,566,561,849 is 109228944.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
688 x 566 x 561 x 849 = 185470746912
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
566 : 1, 2, 283, 566
561 : 1, 3, 11, 17, 33, 51, 187, 561
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,566,561,849, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
566:2x 283
561:3x 11x 17
849:3x 283
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 283 = 1698
Therefore, the value for common factors is 1698.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 185470746912/(1x1698)
LCM = 185470746912/1698
LCM = 109228944
Thus, we can understand that the LCM of 688,566,561,849 is 109228944.
